KENNEDY SPACE CENTER, FLA. - Todd Dugan, United Space Alliance technician, removes the cover from the Orbiter Boom Sensor System in the Remote Manipulator System lab. The OBSS is undergoing final checkout and testing in the lab prior to being transferred to the Orbiter Processing Facility for installation on Space Shuttle Discovery. The 50-foot-long OBSS will be attached to the Remote Manipulator System, or Shuttle arm, and is one of the new safety measures for Return to Flight, equipping the orbiter with cameras and laser systems to inspect the Shuttle's Thermal Protection System while in space. Discovery is slated to fly mission STS-114 once Space Shuttle launches resume. The launch planning window is May 12 to June 3, 2005.
